Systolic and diastolic impairment in cirrhotic cardiomyopathy: insights from a cross-sectional study

Abstract

Cirrhotic cardiomyopathy, an intricate and multifaceted complication of end-stage liver disease, manifests as systolic and diastolic dysfunction in patients without previously diagnosed cardiac disease. Our study aims to investigate the prevalence of systolic and diastolic function in patients with cirrhotic cardiomyopathy in our region. We conducted a cross-sectional study on 68 patients with established cirrhosis, and no overt cardiac manifestations, who consequently underwent 2D echocardiography to quantify systolic and diastolic dysfunction, as defined by the 2019 Cirrhotic Cardiomyopathy Consortium. The severity of cirrhosis was determined using various validated scoring systems. A total of 19 out of 68 (28%) had systolic dysfunction, while 6/68 (9%) had evidence of diastolic dysfunction. Overall prevalence of cirrhotic cardiomyopathy was 23/68 (34%), and the presence of hepatitis C was strongly associated with systolic dysfunction with p-value of 0.007. However, it was not significantly associated with diastolic dysfunction, p-value = 0.59. Logistic regression analysis did not show any significant association between cardiac dysfunction and the severity of liver cirrhosis, as assessed by Child–Pugh, MELD, ALBI, PALBI, portal hypertension, and FIB-4 score (R2 = 3.66, F (13, 39) = 1.33, p = 0.234). Our study reveals a remarkable prevalence of cirrhotic cardiomyopathy, which despite being a frequently occurring phenomenon often goes unrecognized. Lack of correlation with the severity of liver cirrhosis, based on currently available scoring system, suggests either a still poorly understood pathological mechanism or requires the development of a new validated reliable scoring system through multi-center longitudinal studies.
